 # bases-game
 
-An game for revision base 2, 10 and 16 (for my a level)
\ No newline at end of file
+An educational game for revision base 2, 10 and 16 (for my a level)<br/>
+See chapters 28 - 32 (Section 6) of the PG OCR revision guide for Computer Science AS and A level for the "rules"<br/>
+https://www.pgonline.co.uk/resources/computer-science/a-level-ocr/ocr-a-level-textbook/<br/>
+
+# What can you "play" currently?
+ - Conversions between bases (integers)<br/>
+ - Binary addition<br/>
+ - Floating point binary to denery conversion<br/>
+
+ # TODO
+  - Two's complement<br/>
+  - Sign and magnitude<br/>
+  - Negative binary<br/>
+  - Complex binary* <br/>
+
+# Why the fuck is this a thing?
+I was fucking revision my fucking as levels and I wanted a program to auto make binary and other bases questions up so I could just rattle through them so yeah.
